摘　　要：为了研究不同粗糙度表面、载荷与摩擦频率对20CrMnTi钢齿轮磨削表面的摩擦磨损性能影响规律和机理,分别在干接触状态与润滑接触状态下开展了往复滑动摩擦磨损试验。研究结果表明:摩擦系数随着接触表面粗糙度和载荷的增大而增大,但随着摩擦频率的增大而减小;磨损深度随着表面粗糙度、载荷和摩擦频率的增大而增大。因此,在干接触与润滑接触两种状态下,不同粗糙度表面、载荷与摩擦频率对摩擦学特性的影响机制均存在显著的差异。In order to study the friction and wear behavior of 20 CrMnTi steel tooth surface with different roughness,load and friction frequency,the reciprocated sliding friction and wear tests are carried out under the conditions of dry and lubrication contacts.The results show that friction coefficient increases with the increase of surface roughness or load,and decreases with the increase of friction frequency,but the wear depth increases with the increase of surface roughness,load or friction frequency.Therefore,under the conditions of dry and lubrication contacts,the effects of different roughness surface,load or friction frequency on the tribological characteristics are significantly different.
